We may not yet have a flux capacitor for time travel, but we do already have the equivalent of "Mr. Fusion", which if cleverly applied, will enable you to run your car on everyday "trash"-- today. This "magical" device is called a gasifier.  And what it does is called gasification.  The resulting gas goes by the names "wood gas, "producer gas" or "syngas".

Gasification is the use of heat to tranform solid biomass, or other carbonaceous solids, into a synthetic "natural gas like" flammable fuel. Through gasification, we can convert nearly any solid dry organic matter into a clean burning, carbon neutral, gaseous fuel. Whether starting with wood chips or walnut shells, construction debris or agricultural waste, the end product is a flexible gaseous fuel you can burn in your internal combustion engine, cooking stove, furnace or flamethrower. Or in this case, your DeLorean. Well ok, how about a Honda Accord . . .

Sound impossible?

Did you know that over one million vehicles in Europe ran onboard gasifiers during WWII to make fuel from wood and charcoal, as gasoline and diesel were rationed or otherwise unavailable? Long before there was biodiesel and ethanol, we actually succeeded in a large-scale, alternative fuels redeployment-- and one which curiously used only cellulosic biomass, not the oil and sugar based biofuel sources which famously compete with food.

This redeployment was made possible by the gasification of waste biomass, using simple gasifiers about as complex as a traditional wood stove. These small-scale gasifiers are easily reproduced (and improved) today by DIY enthusiasts using simple hammer and wrench technology.

The goal of this project is to show you how to do it - using tools you can find at Sears!

Here's a video of us driving the finished Honda Accord around West Oakland - and over to Sears in downtown to pick up some more tools! Fire was kept only in the gasifier. And everyone made it home with smiles on their faces.




This is a really big project! We split the project into several Instructables to make it easier to understand.

  • This instructable explains how to retrofit a Honda Accord (or nearly any car) with our open source Gasifier Experimenter's Kit (GEK) to power it. In this project we cover modifications to the standard GEK Gasifier that are needed, details specific to its installation into the Honda, and modifications to the Honda itself. All standard GEK Gasifier construction and operation details are covered in the sub-projects below.  You can also check out the home site, with updated instructions, CAD files and pictures since the Instructable below.

Step 1: The Goal: Honda + Gasifier

Picture of The Goal: Honda + Gasifier
1987honda.jpg
We developed the open source Gasifier Experimenter's Kit as a flexible-fuel biomass processor to produce a gaseous fuel (syngas). The syngas produced by our GEK can be used to power generators, heaters and motors (nearly anything that could be run on propane), so we decided to build a concept car powered by our GEK unit.

How does that work?

In a normal car, liquid gasoline is injected into the cylinders while air is sucked in to burn it. The GEK produces a syngas fuel not a liquid - similar to natural gas. So we can't just dump it into the gas tank and run the engine as usual.

What we'll do is to disable the Honda's gasoline fuel injectors and route our syngas in through the engine's air intake. We'll install a somewhat modified version of our standard GEK unit into the trunk area, with a fuel tube going up to the Honda engine in front.

The only modification to the Honda engine is that we disable the fuel injectors, and tee the air intake to allow pulling in our syngas along with the air. In fact, the Honda engine still can be run on gasoline when we are finished - all that's needed is to flip a switch to re-enable the fuel injectors.

Easier said than done! Read on to see how to do it . . . maybe . . .

Step 2: Tools and Parts

Picture of Tools and Parts
IMG_0236.JPG
IMG_0676.JPG
cuttingplates800.jpg
The vehicle was built at the ALL Power Labs shop. We've got a lot of fun tools, but you could build this project with just power tools you'd find at Sears. I'll note what your alternatives are below.

Tools we used:
  • Power tools - we used all of 'em! drill, grinder, reciprocating saw, flashlight, belt sander, circular saw, etc.
  • Socket set, wrench set, vice grips, etc.
  • MIG welder, plasma cutter (hand and CNC). All you really need is MIG and a cutting torch, the rest of it was us just getting fancy. You could also use a reciprocating saw with metal cutting blade instead of a cutting torch, although that would take a bit longer.
  • Bench chop saw with metal cutting blade is helpful but not required
  • Sheet metal cutters, benders, rollers. This is because we fabricated entirely from sheet steel. To avoid the bending and rolling the easy thing is to start with a recycled metal tank as described in step 5.
  • Car jack. We've got the fancy garage type lifter, but any car jack will do.
  • Shop vac to clean up spilled fuel messes, and clean out reactor
  • For the electronics - soldering tools, wire strippers, crimper

Parts:

The complete GEK Gasifier is designed so that it can be constructed from the lowest cost and most commonly available parts. It is nearly all common sheet steel and plumbing parts. The Honda conversion also does not use any expensive or hard to find components - total raw material and parts cost for this project is probably about $1000 if you build everything yourself.

  • You need to supply a working vehicle. We used a 1987 Honda Accord, but most cars should be ok
  • Our GEK Gasifier kit. We supply CAD files so you can fabricate totally from scratch, or you can purchase parts kits from us at various stages of assembly. Fabrication and/or assembly of the GEK using our plans or kits is detailed in our Instructables Series.
  • Miscellaneous plumbing pipes, tubes and ball valves
  • Sheet steel and a few square steel rods
  • Miscellaneous nuts and bolts
  • Reactor Control Unit (parts kit available soon from ALL Power Labs)
  • I'm sure I forgot something :)

Step 3: Safety

There are a lot of potential dangers with this project.

We recommend you always have a responsible adult present when building your Trash Powered Honda.



  • Cars are big! Heavy! And have lots of moving parts that can squash or grind you up!
  • Gasifiers produce gases which are very good for engines, but very bad for humans. Thus please remember the following whenever you run a gasifer

Warning: A gasifier is a dangerous thermo-chemical device. Like most useful tools, it will do damage if used incorrectly. A gasifier purposely generates carbon monoxide and other dangerous volatile organic gases as an interim step before complete combustion of the gas in a flare or engine. Acute exposure to carbon monoxide can be harmful or fatal. It is colorless, odorless, and will quickly colonize your hemoglobin, leaving no sites left for oxygen to land. Exposure to other VOCs is similarly problematic. In short, it is somewhat like smoking cigarettes, just exponentially worse. In fact, a cigarette is an updraft gasifier, a close cousin to what you are building in steel with the GEK

So dont be an idiot. Don't smoke. And certainly don't smoke the equivalent of 100 cigarettes simultaneously by breathing in any leaking gas from your GEK. Always use a gasifier outdoors, and with extensive ventilation. Always stay out of the smoke and/or produced gas before it is combusted. Know that this is NOT typical campfire smoke. Do NOT treat it as if it were. The carbon monoxide concentrations in gasifier gas are higher than in other "smokes". You can get in trouble quickly, usually before you realize it. SO STAY OUT OF GASIFIER GAS AT ALL TIMES.

Always have a fast reacting carbon monoxide meter in the area where you are working. Ideally, hang one on a tether around your neck. Carbon monoxide meters are available at more hardware stores in the smoke detector section.

And remember that with just one extra oxygen, CO becomes CO2. It is a very easy oxidation pathway, thus why syngas burns so cleanly.

Anyone have a Prius we can challenge at the smog shop?

Step 4: History, Theory and Overview

See here for basic information on wood gas and biomass gasification.

The GEK gasifier design is based on a nozzle and constriction (Imbert type) downdraft reactor. This was the typical gasifier reactor type of WWII, and still the usual starting point for generating low tar wood gas to power internal combustion engines. The GEK design combines all common Imbert type variations into a single configurable reactor, with easy adjustability of all critical dimensions. Gasifier geeks will swoon to know that it supports:

  • variable combustion / reduction zone size and shape (tube, bell, inverted V, hourglass)
  • variable air nozzle position and size
  • air preheating (or lack there of)
  • active tar recycling into incoming air
  • variable air injection architecture (air from top, bottom, or side annular ring)
  • "monorator" type condensing hopper
  • rotary grates/stirrer additions

The GEK Imbert reactor standard sizing and configuration is known to produce clean syngas when operated by a knowledgeable enthusiast. This default configuration will run 5-20hp engines. We've expanded the internal sizes for the Honda Accord project so it can support the 70HP or so Honda engine.

The graphics below show the usual components for a full gasification system: Gasifier, cyclone, filter, radiator, fan, burner. The GEK improves on the 60 year old standard a bit, which we will explore in more detail in the Fabricating the GEK Instrucable


Step 5: Different ways to make the GEK

Picture of Different ways to make the GEK
3154343525_6734a9f320.jpg
abram_conehead-800.jpg
IMG_0748.JPG
gekrobot.jpg
The GEK building scenario let's you decide the relative amount of "effort vs cost" you want to invest towards your finished unit. The basic vessel dimensions are based on common scrap tanks found in North America, so you can choose to build it for minimum money with the dimensions, instructions and CAD files provided here. The local junkyard will give you all the greasy obtainium scrap tanks you need. Or you can build the GEK from clean and purpose cut sheetmetal, also using the CAD files provided here.

For the obtainium route, you will need scrap tanks of 10", 12" and 14.75" diameters. 10" is typical for hand held air transfer tanks and some truck pony tanks. 12" is typical for 5 and 10 gal propane tanks. 14.75" is typical for a 100lb/25gal propane tank. (Warning: There's a surprising amount dimensional variation on "standardized tanks" between different tank manufacturers. This can complicate the fit of flanges and end plates to the scrap tanks.)

The more elegant way to build the GEK is from purposed cut and rolled sheetmetal. Sheet metal is still very inexpensive, and you will have better dimensional control than via the obtainium route.

You can cut the sheetmetal to make the vessel tubes, flanges and end plates, using a gas torch or plasma cutter. Potentially even a sawzall, but ugh! Ideally, the tool for the task is CNC plasma cutter, which can run off the CAD files provided here. Many "manufacturing on demand" providers offer cnc plasma cutting services, so you could order in perfectly cut sheet metal to get you started, and not spend all your enthusiasm fighting the prep work. ALL Power Labs can also provide readymade sheet metal and plumbing kits. See here for more information about readymade GEK wood gas kits.

Hopefully one of the above scenarios will find a good match with your abilities, time and money available. Whichever route you choose to build the GEK, the final unit is the same, and thus experiments and customizations are easily sharable across the GEK user community.

Step 6: Fabricating the basic GEK

Picture of Fabricating the basic GEK
gekflangeplatesetupv1.0-800.jpg
gektubessetupv1.0-800.jpg
The standard GEK gasifier system consists of the following seven components. For the Honda GEK we made a few slight changes to the standard GEK design which are noted below (and detailed in later steps here).

Gas making:
1. Gas cowling and ash grate (for honda - cowling built into box, grate has motor mount)
2. Downdraft reactor (for honda: larger reduction bell)
3. Fuel hopper (for honda: shaped to fit behind rear window)

Particulate clean-up:
4. Cyclone (no change)
5. Packed bed filter (no change)

Gas combustion:
6. Centrifugal vac/blower (no change)
7. Swirl burner (no change)

We will be building each of these components separately in a "slight detour Instructable" dedicated to the welding project. After we're finished, we'll return right here to consider the final assembly and preparation for the first test run.

CAD drawings for all the sheet metal parts and assembled vessels are below, as well as on the download page of the main GEK site at: http://gekgasifier.pbworks.com/How-to-Build-and-Run-the-GEK-Gasifier

And now, get you MIG welders ready, its time to fabricate your GEK . . .

Step 7: Assembling the GEK and preparing for fire

Picture of Assembling the GEK and preparing for fire
fullrig2-800.jpg
picture-46.jpg
picture-4.jpg
vid1.jpg
flame2med.jpg
With basic GEK welding complete, now we can assemble and prepare for fire. No Honda is required for this. When you are finished assembling your basic (or modified) GEK, it will look like one of these.

Well, you might have to apply a bit of paint first. You are welcome to paint your GEK in any manner you like. Though we do suggest you use high temp paint commonly found at any auto store. The 500F paint is fine. You do not need the 1200F paint

Once your paint is dry, there are seven components we'll be assembling, just like there were seven components we just welded together:

- Gas Cowling
- Downdraft Reactor Insert
- Cyclone
- Pack Bed Filter
- Axial Fan
- Swirl Burner
- Fuel Hopper

For the standard GEK: the gas cowling, reactor and hopper bolt together into a single vertical assembly. The cyclone, packed bed filter and blower similarly bolt together into a single vertical assembly. These two assemblies attach together via the gas outlet flange to the cyclone. A soft hose attaches the blower to the swirl burner. And then, fire!

The details of how to accomplish this require another "slight Instructable detour", though we promise not to send you through the ringers of previous. You're now through the hard part. It's all downhill coasting from here to 88MPH.

Click here for the GEK final assembly and first firing preparation instructable.

Step 8: Proof of concept testing: first fire

Picture of Proof of concept testing: first fire
IMG_0044.JPG
flame2med.jpg
With the GEK now together, we hooked it up to a prototype of our electronic Reactor Control Unit (described later) and ran the output to a 2kw 4-stroke generator. This was to simulate more or less what we were planning for the Honda. Somewhat surprisingly, it worked!



Here's the separate Instructible for how to start and run a GEK design gasifierstart and run a GEK design gasifier.

Step 9: Prep the Honda Trunk Mount

Picture of Prep the Honda Trunk Mount
IMG_0173.JPG
IMG_0172.JPG
The trunk of the Honda seemed like a good spot to put the GEK!

1) Cut out the trunk floor along the inside of the frame struts

2) Remove the trunk hatch

3) Fabricate 2 heavy duty mounting pins. The mount system allows rotating the mounted GEK for access, then pinning in place during driving.

4) Weld / bolt the mounting pins to the frame struts

Step 10: Fabricate a frame for the gasifier

Picture of Fabricate a frame for the gasifier
IMG_0176.JPG
IMG_0175.JPG
IMG_0179.JPG
IMG_0177.JPG
When we started out, we were going to get a bit fancy and have a hopper alongside the GEK to hold the fuel. This would be great because the GEK heat would help dry the fuel in the hopper, and the form factor would be more compact. Unfortunately - the alongside hopper requires an auger to move the fuel up and over into the GEK reactor, and this auger proved to be a difficult piece of engineering. So you'll see parts of the hopper with auger bits in them, but ultimately we have not yet gotten the auger fully functioning, and it is not needed with a much simpler over-head hopper.

The hopper box frame is sized to hold the GEK, and to fit into the trunk opening in the honda.

Step 11: Install the cyclone

Picture of Install the cyclone
IMG_0227.JPG
IMG_0245.JPG
We started with the standard GEK cyclone, and fitted it into the hopper/box as well.

In the photos here we also dropped the box into the car. Actually to be more accurate, we dropped the car onto the box using a car jack, the box just sat in place.

Step 12: Install the grate, jigglerator, and dump ports

- At the bottom of the GEK cowling is the standard GEK ash grate for holding up the fuel in the gas producing reduction zone, and allowing ash to filter out the catch basin. In a standard GEK the grate has an external bar for turning by hand.

- We connected the grate drive shaft to a windshield wiper motor mounted to the bottom of the box, so that it can be turned automatically. We call it the JIGGLERATOR. although we do love its name, testing of the vehicle showed that at least in city driving, the car bumps around enough by itself to unclog any fuel jams.

- Also on the bottom are dump ports for ash and water condensate from the output syngas.

Step 13: Air Intake With Butterfly Valve

Picture of Air Intake With Butterfly Valve
IMG_0221.JPG
IMG_0220.JPG
IMG_0216.JPG
IMG_0217.JPG
The syngas and air are both going into the Honda engine via the original air intake. That means the Honda engine can no longer control its own fuel/air mix. We built a new air intake with a butterfly valve so that we can control the fuel to air mix ratio.

The fuel to air mix needs adjustment while the car is driving, so we added a servo control which can be operated from the driver seat.

- The new airtake starts with a length of 2" diameter PVC pipe.

- The butterfly valve is a fender washer that matched the ID of the pipe.

- The fender washer is screwed to a 1/4" diameter aluminum rod

- The aluminum rod goes through 2 holes drilled across the pipe

- The servo turns the rod to open and close the valve.

Step 14: Syngas Piping from gasifier in back to engine in front

Picture of Syngas Piping from gasifier in back to engine in front
IMG_0225.JPG
IMG_0238.JPG
IMG_0690.JPG
IMG_0689.JPG
- Chop off the end of the air intake tube from the Honda

- Add a coupler and tee

- The syngas is routed to the back of the car - using flexible tubes in front and in the rear, underneath the car we made a rectangular steel tube for strength. See photo notes.

- Our custom servo controlled butterfly valve is installed as the new air intake. The valve lets us control the fuel to air mix now that both are going into the original air intake.



Step 15: Solid Fuel Auger - Not Used In Current Design

Originally we wanted to have the hopper alongside the GEK reactor to hold the biomass fuel. It had the advantage of a more compact form factor, plus the GEK heat could help dry the fuel to allow using wetter fuels. But, it requires a way to transport the solid biomass fuel up and over to load the GEK reactor

We built several solid fuel augers, but soon discovered that it is a difficult engineering problem when you want to run an auger up from horizontal, or in our case, about 45 degrees. We currently run the vehicle with the typical top-mounted gravity-fed GEK hopper, which is simple and reliable. We hope to get the auger working eventually but for now you can refer to our prototypes and hopefully learn something about all the ways that auger can not work.

We built and tested 2 different auger designs. Generally, they would work for certain fuel size and shape, but when the particulars changed, they would either jam or fail to move/lift the fuel. The GEK reactor will run on a wide range of solid biomass as long as it is chipped or chopped into chunky bits from about 3/8" to 1.5". All diagnoal designs we tested were much more fuel sensitive than the gasifier itself.

Here's a video of one of them running:


Step 16: GEK Reactor Modifications and Instrumentation

Picture of GEK Reactor Modifications and Instrumentation
IMG_0248.JPG
IMG_0051.JPG
IMG_0682.JPG
IMG_0050.JPG
3154343525_6734a9f320.jpg
We made a few changes to the basic GEK reactor design:

- Increased the size of the reduction bell, this increases power output compared to the standard GEK design, which was needed to produce syngas fast enough for the Honda engine

- Added instrumentation - 4 thermocouples and 2 pressure sensors. These aren't really needed for operation, but we built this as a research design so we like to know what is going on inside.

See the photos for how we routed the thermocouples into the GEK so that they are durable and don't interfere with operation.

Step 17: Reactor Control Unit (RCU) - aka "THE BRAIN 2"

Any modern car has an Electronic Control Unit, or ECU, which monitors and controls the engine function and keeps everything working. It is often called the Brain of the car. One of the Honda ECU's main functions is to properly inject gasoline into the engine, and monitor the fuel/air mix. Since we are doing some Serious Monkeying Around with both of those pathways in order to replace the gasoline with our Gasifier produced syngas, we built our own Reactor Control Unit (RCU) - also known as THE BRAIN 2.

The RCU taps into the Honda ECU to bypass its control of the fuel injectors and fuel/air mix. It also has several other functions:

- Sense if the fuel mix is lean or rich. We use the existing oxygen sensor from the Honda and access it where it connects to the Honda ECU (Honda's stock ECU is their brain for running the car).

- Control our new fuel/air mix butterfly valve. We drive a servo from a dial mounted on the dash. We also have a switch on the dash that can toggle between Manual fuel/air mix control, and Automatic fuel/air mix control. In Auto mode our RCU uses a closed-loop feedback to automatically adjust the air/fuel mix, just like the Honda ECU does when running on gasoline.

- A control for the grate jigglerator motor (fuel unclogging system)

- A sensing and control loop for steam injection into the gasifier, when there is adequate heat. The GEK in the this Honda has a variety of heat recycling systems which result in a surplus of heat in the gasifier, heat which can be usefully consumed via more steam over the glowing char in the reactor, and thus a more hydrogen rich gas output.

- A solid fuel level sensor and auger motor control. Not used in the current non-auger design.

- A USB connection to a laptop, we send all the sensor data to the laptop to display it. The Co-pilot can check the readings on all the instrumentation - thermocouples, pressure sensors, oxygen sensor, and all the motors can be activated manually by the copilot.

- A switch to disable or enable the electronic fuel injection. we again tapped into the Honda ECU for this.



Our Reactor Control Unit is built with a SiLabs 8051 devkit with a custom expansion board plugged to it. There are 12 thermocouple jacks, 4 pressure sensors, 4 30-amp H-bridges for motor drive, a USB connection for a data display laptop, etc....

Step 18: Cockpit

Picture of Cockpit
The air/fuel mix knob and manual/auto switch are just next to the wheel for the driver.

The Copilot can watch all the sensors via the laptop display, and make changes to any of the motors or the air/fuel mix as well.

The laptop also logs the readings so we can see what worked and what didn't.


Step 19: Final GEK reassembly for Honda

- Install reactor into cowling (standard GEK method with sealing tape)

- Add perlite between GEK inner and outer cowlings (standard)

- Bolt on the gas filtration unit (standard)

- Bolt hopper on top of reactor. We made a thinner hopper than the standard one so so it fits behind the rear window.



Step 20: Blow-off and output syngas valves

Picture of Blow-off and output syngas valves
IMG_0700.JPG
When starting up the GEK reactor its convenient to be able to get it going without having the Honda engine running. We put a tee on the GEK syngas output so we can send it either to the engine or to cyclone burner flare-off. Once the reactor is up to temperature and running well, we can shut off the cyclone and start the car on syngas.

Step 21: Load Solid Fuel and Ignition!

Hey man, can i borrow your shoes? No? Well, how about some wood chips? Or those peanut shells you are throwing everywhere?

Step 22: Ready!

Picture of Ready!

Step 23: GO! 88MPH here we come . . .

Here's a video of us driving the finished Honda Accord around West Oakland. No shots were fired. Fire was kept only in the gasifier. And everyone made it home with smiles on their faces.

My grandpa always told us about how they used that in Germany during and after the war. He would've loved to see something like this.

nice 'able pretty cool, saw this thing on a tv show once
you should put this on a delorean with a flux capacitor and a time circuit.
awesome i may someday do this because by dad is a mechanic and has his own company

Fantastic 'ible!!! What are some good ways of determining how big the gasifier needs to be to run certain engines, so that I can build one to fit in my car with the least amount of mods. Also, what is the most efficient temperature to run a gasifier. Thanks!
Pignanelli5 years ago
I think what you need is TWO screws, turning against each other (that is, a left-hand screw and a right-hand screw, both moving the material up, and turning in opposite directions). Am I crazy?
two flat rubber belts on a funnel shaped form would do the job pretty well.

This is really cool and everything, and it's a great example, but does anyone else think it's a little pie-in-the-sky for large distribution due to the enormously costly electronic control system? If only someone could come up with a more elegant mechanical control system design, it would reduce the cost by, what? Two thirds? Three quarters?
I doubt it. There is a reason why electronic controls are replacing mechanical ones in homes, cars, industrial devices, really about everything. The electronics may look expensive, but if you tried to do anything similar with mechanical control, I would bet that it would be more expensive. That would be true in one-off (because of the time required to machine the mechanical parts for a custom mechanical control) or mega-scale (because if Honda decided to produce a wood-gasifier car, the control would not cost any more than the ECU that runs the gasoline engine).

I suspect that it seems expensive because you are unconsciously comparing a one-off scale research setup to the prices of mass produced products.
they had a crude version of this that was used extensively during WW 2 in britain. it was I believe manually controlled and many were homebuilt. Check e-bay. I've seen several offering plans or a collection of old data on these for a reasonable price. See my comment above.

awesome piece of work.............
how many days it took for u????????/
wat is ur project cost value??????

gr8 job
If this has existed since WW2, then why don't we see more cars using this or this being suggested as a answer to the carbon emission problems?
According to my reading, the ww2 models were very dirty and had to change or clean filters frequently and they didn't give full power. also since I believe they were manually controlled, it took a bit of a mechanic to keep it running.
in addition, we today are lazy and or in too much of a hurry to go out and build a fire, wait for it to get going etc. before running to town. Stil, I plan to build one.
Actually the carbon emission problems wouldn't be solved. There is just as much carbon in the trash you would burn as there is in gasoline. It would be a bit different but probably be just as much carbon going into the air. The other bad stuff in gas would be gone though, depending, of course, on what you burned in the syngas generator.
the carbon from gasoline is from the ground and goes to the air. while a gassier takes carbon from the air to make biomass and then returns it to the air for no net increase.

This is wrong. The *gassifier takes carbon from the fuel. The difference between using gasoline and trash is that trash would normally go to a landfill and gasoline has to be mined, refined, processed, and transported.

and the carbon in the gassifer fuel came from the air. while in gasoline the carbon came from the earth
Petroleum is fossilize biomass containing trapped carbon. Trash is new biomass containing trapped carbon. The only difference is that this burns new biomass rather than old. Both release carbon and many other harmful emissions.
there's a simple question, how long does the carbon in the fuel take, to return to prefuel state?

if there's plastic in the trash, it's about the same as gasoline, which takes millions of years.
with wood, a few decades.
farm waste that was grasses or seeds, a year, if there's multiple crops, averages to half a year.
algae, depending on the continuous production capability, maybe a few weeks or a month.

the goal is to make the recovery time lower, not to whine about petroleum being the same carbon as in the trash... of course it's the same, but there's millions of years difference there.
Its carbon neutral. Since wood and organic matter decompose over time it releases such gas and this just speeds up the process. Wood stoves are cabon neutral as well. The tree uses Co2 to live and when dead it releases the equivalent amount/
If you bottled the exhaust from this project you could pump it in to An Algae Bio-reactor (As seen in below link ) and run two vehcles on the same carbon there for halving emissions. http://www.instructables.com/id/An-Algae-Bioreactor-from-Recycled-Water-Bottles/
What he means by carbon neutral is that he isn't adding any extra Carbon to the atmosphere. If it is all organic waste, then it just outputs what it took in.
"If this has existed since WW2" What do you mean "if"? Why is it so hard to comprehend that it has occurred to others in the last 500 years to explore technology alternatives in their era when faced with scarcity of supply of standard solutions? The word "hubris" comes to mind. I respectfully submit that you crack a book; do some research. The reason you don't see this tech in use is it is a very inefficient process. You have to heat the material to get the syngas out and that heating process costs a lot. We don't see steam powered trains or cars for nearly the exact same reason. Our current gasoline/diesel refining infrastructure is far far far more efficient. But technology like this does come into its own when that infrastructure is unavailable, but that doesn't mean the cost of using it drops. In short, if you relied on this technology with the same household budget, you'd be taking a lot fewer car rides. The prices of products in any economy transporting goods using steam/syngas technology would cost far more. Shipping a package via UPS would be a luxury. The number of poor people would increase quite a bit I'd estimate as prices rose. But to have these technologies available in a pinch as a stopgap would have a definite coolness factor. Which is exactly the role they played in the WWII era. One might ask why we don't ride horses anymore also as the answer would dovetail with the above quite a bit.
Hubris= Overbearing pride or arrogance. Thanks a lot, mgalyean, however I must point out that that isn't a very respectable answer. However you did answer my question so I thank you for that, and respectfully implore you to take a page from the three who answered before you who did so with a little more consideration to someone a little more naive than them.
according to www.veva.bc.ca/wtw/Tesla_20060719.pdf Second, we know that production of the gas and its transportation to the gas station is on average 81.7% efficient, for a total of 0.28 km/MJ for a Toyota Camry. What is the equivalent for a gassifer?
The gasification process was originally developed in the 1800s to produce town gas for lighting and cooking. Electricity and natural gas later replaced town gas for these applications, but the gasification process has been utilized for the production of synthetic chemicals and fuels since the 1920s. Wood gas generators, called Gasogene or Gazogène, were used to power motor vehicles in Europe during World War II fuel shortages
